17 And when Abram was ninety-nine years old Jehovah appeared to Abram and said to him “I am El Shaddai: walk before me and be conscientious, 2 and I will institute my covenant between me and you, and multiply you very greatly.”
3 And Abram threw himself down on his face; and God spoke with him, saying 4 “There, my covenant shall be with you and you shall be father of a host of nations. 5 And you shall no longer be named Abram: your name shall be Abraham, because I have destined you for father of a host of nations, 6 and I will make you very prolific indeed and make nations of you, and kings shall come from you. 7 And I will establish my covenant between myself and you and your descendants after you, generation after generation, as a perpetual covenant, to let you and your descendants after you have me for your God. 8 And I will give to you and your descendants after you as a perpetual holding the country in which your immigrant life has been spent, all Canaan; and they shall have me for their God.”
9 And God said to Abraham “And you for your part shall keep my covenant, you and your descendants after you, generation after generation. 10 This is my covenant that you are to keep between me and you and your descendants after you, that every male of yours be circumcised: 11 you shall have the flesh of your foreskin circumcised, and it shall be the token of a covenant between me and you; 12 every male of yours shall be circumcised at a week old, generation after generation. Anyone born in the house or bought with money, of all foreigners who are not of your blood, shall be circumcised: 13 anyone born in your house or bought with your money. And you shall have my covenant in your flesh as a perpetual covenant. 14 And a foreskinned male who does not circumcise the flesh of his foreskin, that person shall be cut off from his kinsfolk: he has broken my covenant.”
15 And God said to Abraham “Your wife Sarai shall no longer be named Sarai, for her name is Sarah. 16 And I will bless her, and give you a son from her too, and I will bless her and she shall become nations: there shall be kings out of her.” 17 And Abraham threw himself down on his face and laughed, and said to himself “Will a man a hundred years old have a child born to him? or will Sarah, ninety years old, bear a child?” 18* and Abraham said to God “If only by your favor Ishmaʽel might live!” 19 And God said “Nay, your wife Sarah is to bear you a son, and you shall name him Isaac; and I will establish my covenant with him as a perpetual covenant for his descendants after him. 20 And as to Ishmaʽel I listen to you: here I bless him and will make him prolific and multiply him very greatly: twelve princes he shall beget, and I will make a great nation of him. 21 But my covenant I will establish with Isaac, whom Sarah shall bear to you at this season next year.” 22 And he ended talking with him.
23 And God withdrew from Abraham; and Abraham took his son Ishmaʽel and everybody born in his house and everybody bought with his money, every male among the men of Abraham’s household, and circumcised the flesh of their foreskins that same day when God had talked with him. 24 And Abraham was ninety-nine years old when he had the flesh of his foreskin circumcised; 25 and his son Ishmaʽel was thirteen years old when he had the flesh of his foreskin circumcised; 26 that same day Abraham and his son Ishmaʽel were circumcised, 27 and all the men of his house, those born in the house and those bought with money, were circumcised with him.
